Executive summary
The goal of the present document is to define the measurement of electrical power and energy consumption of ICT
equipment as well as environmental parameters (temperature, hygrometry) in order to improve energy monitoring and
to correlate the power consumption to equipment operation activity (telecom traffic, computation, etc.). It is also to
define the transfer protocol of this measurement data from site to network operation centre. Understanding power
consumption provides the opportunity to reduce energy consumption of equipment and/or the network. Granularity,
measurement period and accuracies are defined to meet these targets. They may depend on equipment types and
location in the different segments of a network (customer termination, access, core, data-centre, etc.). In addition, these
measurements can be used to improve engineering and operation including more accurate dimensioning of power
systems, network evolution modelling and prevision, audit on field, etc.
Modal verbs terminology
In the present document "shall", "shall not", "should", "should not", "may", "need not", "will", "will not", "can" and
"cannot" are to be interpreted as described in clause 3.2 of the ETSI Drafting Rules (Verbal forms for the expression of
provisions).
"must" and "must not" are NOT allowed in ETSI deliverables except when used in direct citation.
Introduction
The present document was developed jointly by ETSI TC EE and ITU-T Study Group 5. It is published respectively by
ITU and ETSI as Recommendation ITU-T L.1396 [i.2] and ETSI ES 202 336-12 [i.16] (the present document), which
are technically-equivalent.
ETSI
6 ETSI ES 202 336-12 V1.3.1 (2025-09)
1 Scope
The present document defines measurement and monitoring of power, energy and environmental parameters for ICT
equipment in telecommunications or data centre or customer premises.
It defines the power, energy and environmental parameters monitoring interface of ICT equipment based on generic
ETSI ES 202 336-1 [1] interface so that correlations can be made with ICT equipment parameters (traffic, flowrate,
number of connected lines, radio setting, QoS KPI, etc.) in the Network Management System (NMS).
Correlations of monitored data (power, energy consumption and environmental values) with other ICT equipment
functional parameters and settings are not in the scope of the present document.
The monitoring interface covers:
• Internal power consumption measurement on the ICT equipment powered in DC and AC.
• Power consumption measurement external to the ICT equipment (if not implemented internally, e.g. legacy
equipment).
• Energy metering based on power consumption measurement.
• Environmental parameters of the ICT equipment (e.g. temperature at air inlet of equipment).
The present document defines:
• The minimum set of exchanged information required at the interface, including parameters such as
measurement type (e.g. RMS), accuracy, range, etc. and settings such as data acquisition and transmission
period, etc. This includes the data preparation, recording and transmission functions.
• The testing method of some parameters and functions.
Text tables in annexes A and B with data exchange described in "natural language".

Executive summary
The goal of the present document is to define the measurement of electrical power and energy consumption of ICT
equipment as well as environmental parameters (temperature, hygrometry) in order to improve energy monitoring and
to correlate the power consumption to equipment operation activity (telecom traffic, computation, etc.). It is also to
define the transfer protocol of this measurement data from site to network operation centre. Understanding power
consumption provides the opportunity to reduce energy consumption of equipment and/or the network. Granularity,
measurement period and accuracies are defined to meet these targets. They may depend on equipment types and
location in the different segments of a network (customer termination, access, core, data-centre, etc.). In addition, these
measurements can be used to improve engineering and operation including more accurate dimensioning of power
systems, network evolution modelling and prevision, audit on field, etc.
Modal verbs terminology
In the present document "shall", "shall not", "should", "should not", "may", "need not", "will", "will not", "can" and
"cannot" are to be interpreted as described in clause 3.2 of the ETSI Drafting Rules (Verbal forms for the expression of
provisions).
"must" and "must not" are NOT allowed in ETSI deliverables except when used in direct citation.
Introduction
The present document was developed jointly by ETSI TC EE and ITU-T Study Group 5. It is published respectively by
ITU and ETSI as Recommendation ITU-T L.1396 [i.2] and ETSI ES 202 336-12 [i.16] (the present document), which
are technically-equivalent.

1 Scope
The present document defines measurement and monitoring of power, energy and environmental parameters for ICT
equipment in telecommunications or data centre or customer premises.
It defines the power, energy and environmental parameters monitoring interface of ICT equipment based on generic
ETSI ES 202 336-1 [1] interface so that correlations can be made with ICT equipment parameters (traffic, flowrate,
number of connected lines, radio setting, QoS KPI, etc.) in the Network Management System (NMS).
Correlations of monitored data (power, energy consumption and environmental values) with other ICT equipment
functional parameters and settings are not in the scope of the present document.
The monitoring interface covers:
• Internal power consumption measurement on the ICT equipment powered in DC and AC.
• Power consumption measurement external to the ICT equipment (if not implemented internally, e.g. legacy
equipment).
• Energy metering based on power consumption measurement.
• Environmental parameters of the ICT equipment (e.g. temperature at air inlet of equipment).
The present document defines:
• The minimum set of exchanged information required at the interface, including parameters such as
measurement type (e.g. RMS), accuracy, range, etc. and settings such as data acquisition and transmission
period, etc. This includes the data preparation, recording and transmission functions.
• The testing method of some parameters and functions.
